Answer:
Step-by-step explanation:
To add two fractions we need a common denominator. Just by looking at the two, there are no common factors. This means the denominator would be the product of the two: 4x(x-8). In order to obtain this, we multiply the first fraction by (x-8)/(x-8) - 1, and the second by 4x/4x - 1:
We can use the distributive property to simplify:
The sum of the two is:

Answer:
see below
Step-by-step explanation:
sqrt(90)
We know that sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9*10)
sqrt(9) sqrt(10)
3*sqrt(10)
The formula
a(n) = 2 - 5(n-1)
is in the form
a(n) = a1 + d(n-1)
where
a1 = first term = 2
d = -5 = common difference
The first term is carried over to the recursive formula. We start with a1 = 2. The next term after that is found by subtracting 5 from the previous term. So
second term = (first term) - 5
third term = (second term) - 5
and so on
The recursive step would be
a(n) = a(n-1)-5
So that's why the answer is choice C
Use a calculator and it would give you 1/20. Best of luck!
